Abstract: An environmental monitoring well housing and protection method.  A housing is disposed over the end of an environmental monitoring well pipe and set in concrete along with the well pipe itself so that the space between the housing and the well pipe is filled with concrete below the end of the well pipe.  Fins extend outwardly from the housing into the concrete to anchor the housing.  The housing has an interior ledge for receiving and supporting a cover.  A flexible gasket is placed on the ledge, the cover is placed on the flexible gasket, and the two are fastened down by a pair of bolts that screw into threaded bores in the ledge.  The bolts have five-sided heads and a special tool is provided for installing and removing them. The cover thickness is substantially the same as the distance from the top of the housing down to the ledge, so that where the top of the housing is mounted flush with the ground the top of the cover is also flush with the ground. The cover includes recesses for the heads of each of the bolts, so that the resultant well head is entirely flush with the surface of the ground.  The flexible gasket has an adhesive material on its underside for attachment to the ledge.  Apertures in the cover through which the bolts extend are sized to receive a tip of the special tool for use in lifting the cover.

Each of the longitudinal members  have  a  first  and  second  support means  which  are opposed and longitudinally spaced from each other.   Each support means include a rod member engaging means operable to receive a rod member when the overlay is moved relatively toward the respective rod member in a direction normal to the plane of the belt.  The first and/or second support means each have a downwardly directed opening extending longitudinally of the longitudinal member and parallel to the plane of the belt allowing the belt to expand or collapse while the belt travels through an arcuate path about an axis parallel to the plane of the belt.  The overlay is releasably clipped onto the rod members with a plurality of rod member retaining means.

Patent CA-2064213-A1 (CA)
Inventor: HENRION W S
IPC: F16F15/073
Filed: 1990-05-25
Abstract: A spring-mass-support structure (36') is arranged as an accelerometer with two electrostatic feedback loops so as to mea-sure two components of acceleration. Two of such accelerometers (1010, 1012) are advantageously used on a submerged platform (1006) to determine the direction of a sound source in a body of water. One of such feedback loops (924, 926, 928, 930, 932) of each accelerometer is used to measure low frequency gravitational acceleration applied to the platform as a result of the tilt of the platform due to the action of current and wave action of the water. The other of the feedback loops (124, 126, 150, 164, 166) of each accelerometer measures sound wave induced acceleration on the platform. The gravitational acceleration of each acceler-ometer is used to compensate the higher frequency acceleration for the effect of tilt of the platform.

Abstract: Hoechst Aktiengesellschaft, Frankfurt am Main 80 Abstract Synthesis gas produced by partial oxidation of ash-rich hydrocarbons with the formation of approximately 0.1 to approximately 0.3  % by weight soot  (relative to the carbon used in the form of hydrocarbons) is cooled first in a radiant cooler and then in a convection cooler.  The raw gas is then washed in a wet separator and, after filtration, the washwater is returned to the gasification plant, if necessary together with the aqueous phase from the radiant cooler.  The water separated from the raw gas saturated with water vapor contains only traces of metals and metal compounds and can be supplied directly to a water treatment plant.

Title: Conveyor belt stripper
Inventor: VEENHOF WILLEM D
IPC: B65G45/12
Filed: 1992-08-20
Abstract: CONVEYOR BELT STRIPPER            Abstract A conveyor belt cleaning assembly (10) includes an array of stripper blocks (24) which are coupled to a rigid crossbar (22) by resilient connecting arms (26).  The resilient connecting arms are characterized by high com-pressive strength,  but exhibit a structural collapsing response to off center deflection forces which exceed a predetermined load level.   The collapsed connecting arms thus provide a reduction in length of the stripper assembly in response to a belt reversing condition.  One side (26A) of each connecting arm has the ability to collapse in response to a relatively low deflection force and the other side (26B) has the ability to deflect and withstand sub-stantial compression loading without collapse.  The body of each connecting arm is intersected by a large aperture (44), thereby defining a forward collapsible wall and a load bearing rear wall. A reduction in length of the entire connecting arm is achieved by collapsing the forward wall in response to the loading imposed by engagement of the stripper block against a reverse moving conveyor belt.
